it is perfectly ok to mix non-batiks with batiks---that latest blue bargello I posted everyone loved so much has more non-batiks than batiks, but has both along with a fairy frost or 2...the thing about a good bargello color run is getting the 'Values' right---going light to dark, with good contrast. if all of your fabrics are mediums you don't get the *drama* . I know everyone is saying to pull those new ones---but I kind of like them- fabrics look so different when cut into a narrow strip- try opening up your fabrics-then laying them on top of each other with only 2" of each showing...that will give you a good idea how they actually will look together
